Offline classification rates after applying the classifier for online use on all time steps between 1 and 5 s after the cue, accuracies at the best points in time, and test results after using validation sets in an outer cross-validation (oCV) routine.

For each subject, one to four features were chosen individually. These were band-powers in frequency bands recorded on the three bipolar channels.
